REGULATOR FOR CHARGING BATTERIES FROM PHOTOVOLTAIC MODULE
WRM60 X
Master
The WRM60 X is a regulator for battery charging with current up to 60A
from two independent MPPT photovoltaic channels. It is compatible with
24/48V nominal voltage lithium smart batteries controlled by CAN BUS
protocol and standard lead batteries by installing the Western Battery
Monitor (WBM).
The Slave (SL) version is a simple recharging unit used for power expansion,
while the Master version integrates not only the recharging unit but also
the control unit needed to create the WESTERN WRD SYSTEM: a flexible
and advanced stand-alone system with data monitoring and remote control
from the internet through the platform my Leonardo. The WBUS is a
proprietary control bus (WESTERN) that communicates with the various
compatible devices and is able to access all the parameters for both
displaying and managing the control functions. Thanks to the WBUS, the
system becomes modular and it is possible to add the WRM60 X Slave
version to the system to obtain charging powers of up to 50kW.
In the Master version, the simple user interface, with a 128x64 display and
4 keys, allows immediate display of all parameters: powers, voltages, PV
string and charge currents, energy meters, data and event loggers. It has
contacts for intelligent activation of loads connected to the system for
efficient battery management.
The removable μSD stores the logger data. Through the
internet connection it is possible to connect to the my Leonardo cloud for
remote monitoring and control of your system.
